Foreword This document (EN 12674-4:2006) has been prepared by Technical Committee CEN/TC 261 Packaging, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2007 and conflicting national standards shall be withdrawn at the latest by June 2007. This European Standard is part of a series of four standards for roll containers and dollies; no existing document is being replaced. The other parts are entitled as follows: Roll containers Part 1: Terminology Roll containers Part 2: General design and safety principles Roll containers Part 3: Test methods According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. 3
Introduction Roll containers and dollies are equipment intended for moving goods. They comprise apparatus fitted with fixed and/or swivel castors. For roll containers the superstructure comprises two or more frames which provide retention for items requiring transport and/or distribution. Dollies and roll containers can be supplied in a variety of materials and additionally roll containers are supplied in four main styles. One of these styles, the nesting style, is further sub-divided into five derived forms and the demountable style is sub-divided into two derived forms. EN 12674-1 gives details of how these styles differ. EN 12674-2 gives methods of measuring working dimensions and aspects of design that manufacturers need to be aware of. Test methods are given in EN 12674-3 which are supported by performance levels in this European Standard, which take account of the normal static and dynamic loads applied in use. This European Standard specifies minimum levels of performance for critical tests, in particular with reference to safety. Certain tests which are related only to longevity, quality control or need development are optional and if carried out may be subject to agreement between manufacturer and user. Tests are applied to fully assembled roll container and dolly specimens as indicated in Table 1. Dismantled or nested roll containers are not subjected to testing; however, empty dollies stacked ready for use, storage or transit are to be subjected to normative testing in order to determine a safe number of stacked units. In order to calculate applied test loads a nominal safe working load (SWL) of 250 kg is assumed in this European Standard for every specimen. The value of 250 kg is not a normative level and may be reduced or increased by the testing body in collaboration with the specimen supplier/manufacturer. However, if different, the level used should be clearly stated in the test report. 4

NOTE 2 Length and width are defined in 4.1 of EN 12674-2:2001. 3.3 angle of inclination (beta) ß angle in a vertical plane, normal to the line of tilt, at which the roll container becomes unstable and topples sideways NOTE Shown in Figures 1a and 1b of EN 12674-3:2004. 3.4 geometric centre centre point in plan elevation generated by the intersection of two imaginary lines from the opposite internal corners of the base 3.5 vertical axis central axis of a roll container or dolly passing through the geometric centre 5
